The nVidia corporation, probably best known for their industry leading video cards like the GeForce, is now marketing a hardware based personal firewall. The nForce comes in two forms - an Ethernet adapter PCI card, and a motherboard with an embedded Ethernet adapter.

The nForce is an ICSA certified firewall, with full firewall functionality, that sits inside your computer.

If you're having a Windows Networking, or file sharing, problem, and you have an nForce component in your computer, you need to know this. During January and February 2006, I assisted in diagnosing several network issues that involved the nForce. In at least one case, the person with the computer had no idea what he had purchased, and innocently installed.

And be aware - the drivers for the nVidia nForce Versions 2, 3, and 4 contain shared components. And the installable component in the firewall, the nVidia Access Manager, has been reported to fail open. That is, if you don't install NAM, or don't activate it, the firewall blocks traffic, and not necessarily all traffic.

Created a test folder on AMD64, with full permissions for everyone>>>>>under "sharing" tab, and with "read" permissions for each user and>>>>>group under the "security" tab. (Some were greyed out).>>>>>4. Activated this user name on each computer with "net user name>>>>>/active:yes">>>>>5. Checked TCP/IP for correct settings and did "repair" to flush.>>>>>6.

Hi Chuck.I went through the process of reinstalling and uninstalling thetroublesome NVIDIA network access manager, just so I could plan a postwith some specific instructions for some unfortunate individual likeme and try to save that person some time and frustration. So I plan topost it as a new topic under the heading

"NVIDIA "hidden firewall" causes networking problem"

I thought it might be more retrievable for someone with a similarproblem if I put NVIDIA in the title of the topic.Many thanks again!

-WoW-Halo PC Servers-another persons webcam or them to mine over yahoo and msn-I can download utorrent, limewire, and bearshare, but they cant connect to the servers to search and download songs.

I have follwed every step in JClark's page but have a few problems:-I have no "Network Access Manager" to remove-I have no need to download the drive program since after i delete nvidia drivers and reboot it, everything is back in place as though it never happened, and when i do run the program, it does not give me an option to deny downloading Nvidia Firewall and Forceware Network Access Manager-I do ot need to reconfigure TCP/IP, cause like I said, everything is back in order.

I did download the proper driver for my OS, which is different then the one JClark used.

If I did not explain anything clearly let me know and I will try to explain it again. Please contact me at lst.angel@hotmail.com

As long as anybody can walk into Sears or
Walmart, and buy a computer or piece of networking gear, take it home,
and install it by herself (himself) there will always be possible
problems. I'll try to help identify the problems, and figure out the
solutions.
